SLVAET0A May 2020 – May 2020 TPS51215A , TPS51285A , TPS51367
Table 1 highlights the latest POL DC/DC converters with integrated MOSFETs and controllers suitable for Elkhart Lake applications. The suggested devices are selected to accommodate different input voltage and control mode requirements over a wide range of output current. The featured devices in the left-hand column accommodate a maximum input voltage of 22V or greater, and are designed to achieve fast load-transient response with an adaptive on-time control mode, high light and full-load efficiency, and low quiescent current. Several devices include an integrated programmable voltage identification (VID) supporting the processor's adaptive voltage requirements. The alternate devices in the right-hand column employ a fixed-frequency control mode with frequency synchronization useful in noise-sensitive industrial applications. If VID is required with alternative devices, consider the LM10011 VID voltage programmer in addition to the converter's resistor divider network.
